Application of Medium Load Disc Spring in Industrial Valve

Application of Medium Load Disc Spring in Industrial Valve

Medium-load disc springs play a pivotal role in industrial valves, particularly in applications requiring high reliability and extended service life. These springs are primarily used for sealing pre-tightening and stroke reset functions in industrial valves, with stringent technical requirements for load stability, fatigue resistance, and anti-relaxation properties. The DIN2093-compliant medium-load disc spring series, renowned for its exceptional mechanical performance and durability, has been widely adopted in various valve actuators, demonstrating exceptional reliability and stability.

The product focus is currently on the 001 028 and 001 045 series, featuring a nominal diameter D of 12.516mm, suitable for various industrial valve applications. Taking the 001 031A as an example, its technical specifications are as follows: outer diameter D = 14.00mm, inner diameter d = 7.20mm, thickness t = 0.80mm, and free height H₀ = 1.10mm. The load capacity reaches 284N at 25% compression stroke, and increases to 547N at 50% compression, demonstrating excellent linear elastic characteristics.

In practical valve applications, disc springs are typically employed in either paired or stacked configurations to meet diverse spatial and mechanical requirements. A single disc spring can provide hundreds of Newtons of preload force, and through flexible combinations of varying numbers and configurations, they can adapt to sealing pressure demands across multiple valve specifications. Additionally, this series of disc springs demonstrates exceptional stress relaxation resistance, maintaining consistent sealing force under long-term operation and temperature fluctuations. This ensures reliable valve system performance while eliminating leakage risks.

The key features of the valve include: providing long-lasting and stable sealing preload; excellent temperature resistance across a wide operating range from-20°C to +120°C; outstanding anti-relaxation performance for prolonged pressure applications; and flexible modular configurations that can be customized to meet specific valve size and pressure requirements.
